There is. In the app, under Noise Control, we have ADAPTIVE, CUSTOM, or OFF. I was wondering if the measurements were made on OFF, Custom (which can be set from 0% NC to 100%) or ADAPTIVE. I assume adaptive?
No I am aware there is an ANC OFF mode. I’m saying the device itself is always active, meaning there’s no separate passive acoustic only tuning to consider. And to answer your question, yes it’s in adaptive.
Oh, then let me offer a bit of context as to why I asked - apparently, there IS a difference between ANC on (meaning either ADAPTIVE or CUSTOM) and OFF. SoundGuys measured it, and they have this graph (below). That’s why I was wondering how you measured it.
As a sidenote, since in your review you compared the stock HDB 630 EQ with the Dynamic one on the Bathys MG - I was wondering if you did this comparison with a custom PEQ of your liking and what was your conclusion.
10x a lot for your content!

Interesting - thanks for sharing this! It looks like it’s a change to the acoustic z as a function of the ANC, which I suppose is to be expected, though it’s usually a good idea for always active devices try to compensate for this with their DSP (like the Bathys for example). I wonder if they just felt it was better anyway where most people would be using it with ANC on. I’ll look into this and then update this thread here with some data.

I don’t know if it’s vacuum/sucking my right ear or there’s just a channel imbalance, but the right side on my unit sound considerably less loud than the left earcup. But then again, it feels like it’s kinda vacuum sucking my ear? Never experienced it before lol.
They should be under warranty if the problem is consistent, and I believe there’s an method to contact Sennheiser support in SmartControl+’s settings. Another possibility would be the vendor you purchased from, whom typical allow for two weeks.
One thing you can provide for them is a measure of how far from center a mono recording is to your ears.

Turn the headphones around and put them on backwards. If the right ear still sounds quieter, it’s the vacuum sucking your ear, and you need to see an electrician immediately.
@Resolve Any chance to get an updated version of the chart showing ANC performance, between the HDB 630 & Sony WH-1000XM6, to also include the Bose QC Ultra Gen 2?
I want to replace my WH-1000XM4’s, and I was going to go with the HDB 630 until your latest video on the Bose. I think I’d prefer the 630’s but would like to see the ANC performance side be side. This is primarily for travel, but I love the idea of dialing in the sound signature with a PEQ.
It’s kind of impossible to visualize the QC Ultra Gen 2’s actual ANC performance because it’s adaptive in nature. I’ll have to come up with a better way of visualizing ANC performance generally, especially since this tends to be the way things are going with this technology.
But, for ANC performance specifically, I still think of it like this:
WH1000XM6 > Bose QC Ultra > > HDB 630

Thank you! Similar to my experience with the Sennheiser PXC 550. Solid sound quality, especially for a decade ago, but lacking in ANC compared to Sony and Bose.
Guess I’ll just stick with my XM4s for a bit longer, since they’re still pretty close to the latest gen.
Anyone have any clue what’s going on with Headphones.com shipments on these? I ordered mine a month ago and still no update. Emailed a while back and they refuse to give details. I now see best buy has them in stock for order with pickup within a week. Getting pretty frustrated by the lack of clear communication and now seeing a retailer has them in stock.
What’s everyone doing for EQ? The default tuning sounds so correct that I left it alone until recently. I wanted to stick to EQing based on music listening impressions and only refer the measurements to help decide what adjustment to make. More experienced listeners probably wouldn’t need weeks of listening, but 
I eventually decided that the neutral profile sounds a bit clinical, so I added a 3db peak filter at 80 Hz with Q 0.7 to warm things up.
I’m not sold on the exact values, but I do like the warmth it adds, so I’ll keep playing with the values. It’s almost too much on some songs, but 2db is too little on other songs.
Just curious if anyone else has made any adjustments to target specific things their ears are telling them and what the results sound like.
I guess it would ultimately depend on what you’re perceiving as the “problem” area of the bass frequencies, are you looking for more general “warmth” or more “thump”. If it’s more warmth I would maybe scoot a 2 db bell with a wide q around 120hz.
if it’s thump, I’d move it down to 60hz
If it’s just more of all of it. Changing it to a shelf at 120 instead of a bell might just warm the whole bottom end up a bit without being overbearing.
Though this will not be universal as many albums are mixed with very different principals on their low end.
That’s why I’d almost lean towards the small shelf from 120 on down, over a bell.
PSA: the full dB value you want to apply with a shelf filter will not hit at the cutoff frequency you set, you will only get half the dB at the cutoff. So you can’t just switch from a peak/bell type filter to a shelf, keep the same frequency setting and hope to just extend the effects to other frequencies. The cutoff is in the middle of the ramp toward the flat shelf region, not at the top. In this case you’d get +1 dB at 120 Hz vs. the initial +2, if you just switch from a bell to a shelf. 
If you still want the full dB boost to affect the 120 Hz point you have to move the cutoff up by some amount, not easy to calculate with any simple formula, ideally you’d use an EQ that shows you a graph for the filter you’re adjusting so you can include/exclude frequencies as desired.
Great advice from both of you. Thank you! The peak filter seems to be what I need: the shelf boosts sub-bass as well which I don’t want. The thing I hear, at least at lower volumes is similar to the IEM bass shelf dip that supposedly increases separation, but I hear it as thin. Might be why I hear the Truthear Pure as natural compared to IEMs with that dip.
+2 db/Q 0.5 at 120 Hz seems about right at the moment. Some tracks are better if I slide the filter over towards 200 Hz, while others become a bit congested. Different mixes, I guess.
Sennheiser did a pretty nice job with the app, BTW.
Sliding the filter left and right is responsive. Great to be able to do that and hear the effects immediately. Also super useful to be able to hold down the toggle to quickly confirm that the feature I’m trying to EQ returns when I toggle EQ off.
They should have advertised the parametric EQ as a learning tool

Correct. That’s why I suggested 120 hz and not anything lower. Also, Q can greatly effect how steep the frequency boost ramps to the full value. Not sure how it’s implemented with Sennheisers app, but generally, higher Q with a a shelf will make the ramp up steeper.
Looking for advice and info about recording / tracking music with these headphones. There’s a wired USB - C but there’s also a 2.5mm to 3.5mm cable yes? Any latency with either? Does the set tuning and EQ carry over with 2.5mm connection? More extreme case - might the active headphone create any noise used in a multi headphone mixer / splitter situation?
If it is OK (not sure to which extent it would break any rule of the forum) I can post the FR digitized (by hand) from the picture that has been posted here. I made the left, right and average (by eyeballing). This FR is compatible with squiglink.
its the shittiest headphones i’ve ever bought. It keeps changing my sound from background turning it on and off at random making it sound like im in a tin can. acidentally tapping it turns it off or turns it into a submarine. Not worth it, shitty smart headphones

Granted, buttons would’ve been a better option. My own personal beef as to why these will never be considered audiophile quality is volume control. The touch control is too imprecise, and the volume step must be near 3db.
Still, when these cans are dialed in, they’re comfortable enough for several hours, as is the listening experience, plus the most accurate/natural timbre in a closed-back. The best source I’ve found the listerning experience in an Android phone/DAP employing UAPP app for best control of the DSP, whether it’s with the BTD dongle or the USB cable…
